Product Description
Ideal for college students, engineers, surveyors, and medical personnel, the HP 35s scientific calculator offers calculation versatility in one economical unit. For added versatility, the HP 35s lets users choose between RPN or algebraic entry-system logic (no other scientific calculator offers both). It also features a large, two-line alphanumeric display to view entries, results, menus, and prompts with ease. The display also sports an adjustable contrast feature, making it ideal to use both indoors and out. A robust library of 100+ built-in functions and constants also comes pre-loaded for immediate use right out of the box. A robust memory ensures even the largest calculations go smoothly and quickly, and more than 800 independent storage registers allow users to store an equation, then use it again to solve any variable, or employ the equation in conjunction with any of the 100+ built-in functions. The calculator is backed by a manufacturer's 1-year limited warranty.

Reader Reviews
This is a very nice high-quality scientific calculator from HP. The overall design and capabilities are similar to the HP 32SII (equation solver, unit conversions, etc.), but with several enhancements. Like many recent HP models, this calculator can work in either RPN or algebraic mode, but I use only RPN. The keyboard layout has been well thought out, with most functions being quickly available directly from the keyboard and a few lesser-used functions available through menus. The keyboard has a traditional HP layout and colors, and the keys have a nice positive feel. A very thorough and well-written printed manual is included. A new feature with this model is that each level in the four-level stack may hold a real number, complex number, or 2- or 3-element vector. Complex numbers may be entered very simply using the "i" key (or "theta" key for polar form); vectors are entered using square brackets. This design makes it very easy to manipulate complex numbers and vectors. The calculator includes thirty kB of memory, which is enough for over 20,000 program steps. There are 26 main memory registers (A-Z), six statistical registers, and 800 more memory registers available through indirect addressing. Another new feature of this model is TWO indirect registers, (I) and (J). A few cons: With previous HP calculators, there was a shortcut for entering exact powers of 10: for example, 10,000 could be entered as "E 4". For some reason HP has dropped that feature on the 35S, so you now have to enter "1 E 4". Not a major drawback, but kind of annoying since I used that shortcut a lot on previous models. Another nit is that the function to convert HMS to decimal hours is labeled HMS-
